NON-REFILLABLE EQeTTLE.

Specification of Letters Patent.

Patented Sept. 17,1918.

Application filed October 10, 1916. i Serial No. 124,838.

veniently dispensed after which the bottle 7 will be renderedpractically useless by virtue of the structure within the neck of thebottle obviating the possibility of conveniently refilling the same.

One of the objects of the invention resides in the provision of aplurality of valve elements arranged to permit the contents to be easilydispensed and which will automatically seat themselves for preventingrefilling of the bottle.

The above and additional objects are accomplished by such means as areillustrated in the preferred embodiment and in the accompanyingdrawings, wherein like characters denote like or corresponding partsthroughout the several views, in which;

Figure 1 is a longitudinal fragmentary section through a bottle showingmy invention applied thereto, and illustrating the same in uprightposition.

Fig. 2 is a similar view showing the bottle tilted for permitting thecontents to be dispensed.

Fig. 3 is a detail perspective view of the bottle cap.

Referring to the drawing, wherein is illustrated the preferred form ofmy invention, and in which like numerals of reference indicatecorresponding parts throughout the several views, the bottle is providedwith the usual neck 1 having its upper end open and provided withinterior screw threads 2 which extend inwardly of the bottle neck for ashort distance and beyond which the inner wall of the bottle neck issmooth and extends to a shoulder 3 formed by a restricted opening 4which establishes communication with a substantially spherical valvereceiving recess or chamber 5. Communication between the interior of thebody of the bottle and the chamber 5 is established by a restrictedpassageway 6 and the point at which this passageway 6 joins the chamber5 is beveled to provide a valve seat 7 for receiving a ball valve 8 whenthe bottle is in upright position. The ball valve 8 is smaller indiameter than the spherical valve chamber 5 for the purpose ofpermitting the spherical valve to be unseated thuspermitting thecontents of the bottle to be dispensed throughthe openings provided forits exit. The longitudinal valve member 9 is arranged within the neck 1,in the enlarged portion thereof and has. a hollow chamber 10 largeenough to permit a second ball valve 11 to play freely within thechamber when the same is unseated. De-

pending from the member 9 are the side arms 12 which carry the plate 13adapted to project into the chamber 5 since the arms 12 are fitted toproject through the restricted opening 4:. Thus the ball valve 8 isprevented from closing the restricted opening 1 when the bottle istilted.

The bottom of the chamber 10 has a valve seat 14 into which the valve 11is seated when the bottle is in upright position. The upper end of thechamber 9 opens through an opening 15 in the top of the member 9 and itwill be observed that this top terminates slightly below the screwthreads 2.

A cap 15 of the same diameter as the outside diameter of the neck of thebottle is arranged on the top of the neck and has a central recess forreceiving the cork 16. A screw threaded stud 17 is carried by the capand fits into the top of the neck 1 and has screw threaded engagementwith the interior threads 2. Below the stud 17 is a restricting sleeve18 having its terminal disposed at about the center of the member 9 andthe sleeve is cut-out to provide the side openings 19 which communicatewith the interior of the cap whereby the liquid will be permitted'topass from the chamber 10 into the interior of the cap and out of the endthereof when the cork 16 is removed; The disposition of the end ofthesleeve 18 is such as to prevent the ball 11 from falling into a positionwhere it might close the opening in the cap and, therefore, the contentsmay be freely dispensed at all times regardless of the angle at whichthe bottle is tilted.

From the foregoing it will be observed that a very simple and durablenon-refillable bottle has been provided, the details of which embody thepreferred form. I desire it to be understood however, that slightchanges in the minor details of construction may be made withoutdeparting from the spirit of the invention or the scope of the claimhereunto appended.

I claim:

The combination with a bottle neck provided with a spherical valvereceiving recess and a restricted opening establishing communicationbetween the said recess and outlet passage way in the neck, the outerendof the latter being provided with interior screw threads, of a ballvalve of a diameter less than the said restricted opening, and mountedin the said recess, a valve -member mounted in the passage way in theneck and having one terminal provided with arms extended through thesaid restricted opening and carrying a plate disposed in the said recessfor engagement with the ball valve when the bottle is tilted, theinterior of the said valve member having a chamber,

a second ball valve mounted in the chamber gage the said second ballvalve when the bottle is tilted.

In testimony whereof I aifiX my signature in presence of two witnesses.
